Handover ceremony of the safety certificate for trial operation of the western section of Zhengzhou Line 6 Phase I was grandly held

On the morning of October 12, the handover ceremony of the safety certificate for trial off load operation of the signaling system of the western section of Zhengzhou Rail Transit Line 6 Phase I was held in Zhengzhou Rail Building. The handover ceremony was attended by Yang Yong, Deputy Secretary of the Party Committee and General Manager of Zhengzhou Metro Group, Zhao Yunchen, Member of the Party Committee and Chief Engineer of the Group, main principals of the Group’s Construction Branch, Operation Branch, Technical Management Department and Electrical and Mechanical Equipment Department, Liu Jin, Vice President and Chief Operation Officer of Thales SEC Transport and Mao Yao, Project Director, and representatives of participating units, including China Railway Communication and Sigal Survey & Design Institute Co. Ltd., China Railway First Group Electrical Engineering Co., Ltd., and Shanghai Sanwei Project Management and Consultant Co. Ltd.

Zhengzhou Line 6 is the first line built by Thales SEC Transport in Zhengzhou, and it is also the first line which employs Thales SEC Transport’s independent innovation of dual CBTC (TSTCBTC®2.0) system outside Shanghai. The CBTC®2.0 system has the advantages of train control interlocking integration, dual CBTC redundant architecture, two-way ATO driving at any position on the line, and efficient turnback. It is a key strategic project of Thales SEC Transport. Therefore, the company’s management has paid high attention and support to the construction of Zhengzhou Line 6. Thanks to the strong leadership of Zhengzhou Metro Group and with the strong support of all participating units, the project department has adhered to high standards, adopt stringent requirements, made meticulous organization, and arrange in a science-based way, and successfully completed the following key milestones as scheduled:


  • Obtained the certificate of authority for main line interlocking on May 27, 2021;
  • Obtained the certificate of authorization for the Jayu Parking Interlocking on July 9, 2021;
  • Obtained the multi-vehicle high speed train safety certificate on September 30, 2021;
  • Obtained the safety certificate for trial off load operation on October 7, 2021.

Since the commissioning of high speed train, the project team has rose to challenges, made organizations carefully, raced against time to meet deadlines of the schedule in an orderly manner. With the active response and close cooperation of the supporting team, the team has jointly overcome the adverse impact of the epidemic on the construction schedule. Within less than 40 days, they completed the task of commissioning the safety function of the CBTC®2.0 system, and obtained the safety certificate for trial off load operation in advance, marking a phased victory of this project.

As the trial operation is imminent, all staff of the project department of Line 6 will continue to carry forward the fine tradition of “being courageous enough to fight hard battles”, strictly perform project management, pay close attention to on-site safety and engineering quality to help put Zhengzhou Line 6 Phase I into operation with high quality!
